Additional Notes

The Town of Sumner (Trempealeau County) delegates UDC/building-permit administration to the Trempealeau County Dept. of Land Management (applications mailed to the Courthouse, 18600 Hobson St, Whitehall WI 54773-8614); the WI DSPS 'Municipalities with Delegated Authority for the UDC' list (dated 8/19/2026) confirms 'See County of Trempealeau' as the inspector entry for this town. No online permit portal was found — mail-in applications only. HEDGE: Town Clerk contact could not be fully reconciled between two official sources — co.trempealeau.wi.us lists Kalynn Dewitz, clerk@townofsumner.wi.gov, 715-586-3333, 14350 5th Street (Cty Rd O), Osseo WI 54758; the DSPS list instead names a 'Jane Brown, Clerk' at 715-597-3062 / janebrowne@centurytel.net for this same town. Both are included for completeness; verify current clerk before relying on either. IMPORTANT: do NOT confuse with the unrelated Town of Sumner in Barron County or the Town of Sumner in Jefferson County — the Jefferson County one uses a similarly named site (sumner-jc-wi.gov) and a General Engineering Co. permit portal that is NOT this municipality.

What You Need Before Applying for a Permit

Most building departments ask for the same core package before they'll issue a permit: a completed application naming the property owner and contractor, the contractor's state license number and proof of insurance (general liability, and workers' comp if employees are on the job), a notice of commencement or equivalent recorded filing for larger jobs where the state requires one, and scaled plans or a site plan for anything beyond minor repairs. Roofing, fence, pool, and solar permits typically have their own simplified checklists — Town of Sumner's department (above) can confirm exactly what applies to your project.

Why this matters for insurance: permit history is one of the first things an underwriter or adjuster checks. Unpermitted work — a finished basement, an added bedroom, a rebuilt roof — can complicate a claim or even void coverage for that portion of the loss, and it routinely surfaces during a home inspection. Pulling the right permit up front, and keeping the closed-permit record on file, protects both the property's value and its insurability at resale.
